(Okay, this time it's not because of a saved-game issue)
Anyways, with the standard German uniform model, there's two issues with NCOs: (1) NCOs are not wearing the new NCO uniform texture (which is easily identified by the shoulder insignia) and (2) Unterfeldwebels are wearing Gefreiter sleeve insignia.
That's the only uniform anomaly I've noticed so far. Otherwise, the uniform improvements look great.
